Yes, you can pump up a car tire by hand
Don’t get me wrong, this is by no means a spectacular feat of any sort, just a fun little side note. Today when I ventured out to my car I discovered I had a flat front tire. Not having a spare and thinking logically figured I could use my bike tire pump to rectify this problem. Long story short it worked, but it took about 45 minutes and a whole lot of pumping.
